When using external user registration, iHub does not support the special user with the name anonymous. If no Open Security is used, and the anonymous user is present with no assigned password in the Encyclopedia volume, the anonymous user is used as a default login for the Encyclopedia volume.

When using external user registration, a developer must set up the external security source and RSSE application to support connecting as anonymous. To do so, the RSSE application must accept a login with the user name anonymous and no password.
